The ProTouch StageOperator is suitable for safe installation operations featuring fixed- or variable-speed chain hoists and a variety of stage drives such as winches, tubular shaft hoists and lifting platforms.
The system offers integrated group shutdown, which means that whenever limits are exceeded or the safety devices of one drive respond, the entire group or all the drives in motion are stopped.
The controller evaluates all the limit switches of the drives, whilst sensors such as incremental or absolute encoders, load-measuring cells and thermo switches are reliably processed, to guarantee the safe operation of lifting appliances. Using a wide variety of technologies and mediums of data transmission, both centralized and decentralized systems can be produced.
In the Qatar National Convention Center, an entire system with 1752 ChainMaster VarioLifts was installed in seven halls, with control provided by ten 8.4-inch radio controllers.
